Page xiii - First, it should teach the reader how to transform realistic, qualitatively described problems into quantifiably solvable form and to arrive at an approximate solution. Second, it should teach concepts in environmental science from the novel perspective of problem solving.
Page 128 - N is the number of radioactive atoms present at time t, N0 is the number present at time zero, and e is the base of natural logarithms.

Page xiii - Milk production at a dairy farm was low so the farmer wrote to the local university, asking help from academia. A multidisciplinary team of professors was assembled, headed by a theoretical physicist, and two weeks of intensive on-site investigation took place. The scholars then returned to the university, notebooks crammed with data, where the task of writing the report was left to the team leader. Shortly thereafter the farmer received the write-up, and opened it to read on the first line: "Consider...
